I'd guess (and I am guessing, so I might be wrong) that one of the drives is going bad; if you take this out of the RAID configuration, the other drive should work in read/write mode again. How to tell which drive is playing up is another question, dmesg might help, or /var/log/warn, or maybe your raid setup has a log file.

RAID isn't a magic bullet unfortunately, particulary not software raid, which has caused me a fair bit of pain in the past.
